** Tags added: apport-collected

** Description changed:

  I have noticed first that I have bad keyboard response. When I leave a
  key pressed, I have had pause every few seconds ...
  
  That problem disappeared when I have unloaded acer_wmi module.
  
  But high load, and bad machine response stayed.
  
  For example, when I type this text i firefox, and leave a key pressed I
  have about 50% load on both of cpu-s !
  
  When I boot with acpi=off, that high CPU load disappears,  but this is
  notebook - it is unusable without acpi (poweroff, suspend etc ...)
  
  I have also registered this.
  
  $ dmesg | greo storm
  
  [    1.029542] ACPI: EC: GPE storm detected, transactions will use
  polling mode
  
  Also, I have 1 ERR on interrupts:
